To all whomvlt mag concern}: I

Be it known .thatI, PE RL STUBBS, a subject of the Kingof Great Britain, of the town of Lethbridge, Province of Alberta, Dominionof Canada, have invented certain new and useful'Improve ments in Drinking-Cups, of which the following is aspecification;

My invention relates to improvementsin" drinking cups, an-d'theobject of my invene tion is to provide a drinking cup which is made in such form that it can .be Carried aroundfby an individual for personal use only, and since the,cup is designed to be folded and held closed .by a suitable fastening means, it is very neatand compact, and

1 can be readily carriedinthegvest pocket, or in a ladys purse. Another ,ob ect of the. invention is to deslgn a cup or the class set unfolded. Fig. 4 is a view of my cup showing the same spread open flat. Fig. 5 is a view of the upper portion of my cup showing the mouth thereof in position for use when the cup contains liquld, and 6 IS a plan view of the piece of material from which the cup may be made showing the various folds necessary.

In the drawings, like characters of reference refer to the same parts.

As far as I am aware, no individual drinking cup has been provided whlch, when folded, makes its own case, and

which can be used by an individual for a considerable length of time, with care.

Although various types of perlshable drinking cups are on the market, frequently in traveling one is not always able to locate such, and if the individual carries the drinking cup in compact form, the article will always be at hand. v

The advantages of individual drinking cups are too well known in the art to require elaboration, but it will be understood that my drinking cup will be made out of suitable flexible material, and the range Specificationof Letters Patent; I Patented 00175 19, 1920.

thereof. is so very largethat only a few of A i the suitable materials need be mentioned, for instance, rubberized fabrics, oiled cloths, andoiled papers .or linen... i

In making my cup, I take a piece of suitable material A, substantially square in I form as shown .in Fig. 6, and fold over the edges of two adjacent sides thereof thus formin hems B and G. The corner pieces D and of the piece of material A are then folded inwardly along the divergingjlines 1 F, which commence at the corner 10 which is diagonally opposite the corner 11,.the side of oneof said corner-pieces overlapping the other, as shown at G, in Fig. 4C, so

that the said corner pieces may be perma nently coupledtogether to effect the purpose in view. The corner-piecesH of the nowformed-cup are folded along the scoredilines I, I, and I, so that when the cup is opened out in the shape illustrated in Fig. 5, a side flange J will be formed composed of flaps J and J", separated by dotted line I these flaps fold inwardly, the flap J" folding down upon the flap J. These flaps extend longitudinally of the lip K for the desired portion of its length, and as the width of this lip and the length thereof projecting beyond the side flanges J will be suitably proportioned for use, the said side flanges will prevent the liquid from escaping laterally from said lip when drinking. This feature is a very valuable one when used by invalids lying down.

To fold the cup completely, the same is folded along the dotted lines 2 and 3, and the lower end 4 of the cup is folded against the lower intermediate portion 5 of said cup, and said portion 5 is folded against the upper intermediate portion 6, as shown clearly in Fig. 3, and then the corner-pieces H are folded against the lower end 4 and portion 5 and then the flap or lip K is folded along the line 7, thus moving the said flanges J down against the corner-pieces H. 1

Any suitable type of fastening means may be employed: a well-known form of this means comprises a dome 8 carried'by the upper end of the lip K, and the same en- 7 gages with the stud 9 carried by'the lower intermediate portion 5.

Without further elaboration, it will be after use the same can be readily drained, and then folded up to be put away.

It will be observed that in my cup, the lip K is bi-functional, that is, it not only serves as a guiding means to the mouth of the fluid being-consumed, but it also actsas a ,flap

whereby the folded cup is fastened closed,

' with" the device.

While I have described what I consider to be the best embodiment of my invention stillI desire it to be understood that the, V principle may be embodied in other different forms, and I desire not to be limited be 1 yond the requirements of the prior art and the terms of my claims,

' What I claim is: v

1. As a new article of manufacture, a folding vessel made from one piece of suitable flexible material, folded to form, and

provided with a lip extending longitudinally thereof for conveying purp0ses, said lip performing the function of a'retalning flap when said vessel is completely folded, and two inwardly-folding side flanges integrally formed with said lip to extend longitudinally thereof when opened, and positioned one at each side of said lip;

2. As a new article of manufacture, a folding vessel made of one piece of suitable flexible Y material substantially square in form and folded down at two adj aeent sides so as to form hems, certain opposite cornerpie ces of said material being folded along diverging folds from the corner'of said ma terial diagonallyopposite the corner where the ends of said'hem overlap, thus complet-:

ing the formation of the, body portion of the vessel, the overlapping edgesof said cornerpieces being secured together; the upper corner-pieces of said body portion, together with portion of said material, extending beyond said body portion, being folded each along three converging folds thus forming a lip at each sideof which is located flanges each composed oftwo flaps which fold'one upon the other. when the vesselis closed.
